Nozzle Head Pressure Balancing for Inner Glass Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for cleaning glass elements, such as glass tubes, are inefficient in removing particles from the inner surfaces, leading to contamination, especially in longer tubes, and result in noise emissions and uneven cleaning due to the directional flow of air, which can reintroduce dust and fail to interact effectively with particles further from the end sections.
Innovation Solution
A nozzle head design with cleaning and pressure balancing openings that direct fluid flow backward within the glass element, allowing for efficient particle removal by blowing them towards the closer end section, preventing external contamination and ensuring thorough cleaning without creating negative pressure, thus maintaining a clean environment and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pressurized air is injected into the glass tube from one end to blow particles out, then particles can be removed from the inner surface, but the flow velocity decreases over distance and particles farther from the end section are not effectively cleaned
Solution Approach 1:
The nozzle head is divided into multiple functional sections: a first nozzle section with first openings facing the end section, a second nozzle section with second openings facing the middle section, and a third nozzle section with third openings facing the other end section. This segmentation allows different regions of the glass tube to be cleaned by dedicated nozzle sections, maintaining effective cleaning velocity across the entire length.
Solution Approach 2:
The invention transitions from a single-direction linear flow approach to a multi-directional approach by positioning nozzle sections at different locations and orientations. The nozzle head can be positioned at various angles (0°, 45°, 90°, 135°) relative to the glass tube axis, creating fluid streams that interact with particles from multiple spatial dimensions simultaneously.
2Manufacturing precision
If high pressure air is used to blow particles out, then particle removal is effective, but noise emissions increase
Solution Approach 1:
The high-pressure fluid stream is segmented into multiple lower-pressure streams by distributing the flow through multiple nozzle openings (first, second, and third openings) positioned at different locations. This segmentation reduces the pressure and noise of each individual stream while collectively maintaining effective particle removal capability.
3Manufacturing precision
If air is blown from one end through the middle section to the other end, then particles are removed, but the middle section becomes more contaminated
Solution Approach 1:
The cleaning process is segmented into three independent zones: end section cleaning by first openings, middle section cleaning by second openings, and other end section cleaning by third openings. This prevents cross-contamination by ensuring that fluid streams are directed toward specific regions without passing through previously cleaned areas.
Solution Approach 2:
Instead of blowing air from one end through the entire length (which pushes particles through the middle section), the invention inverts the approach by positioning nozzle sections to blow air from multiple locations simultaneously toward their respective target regions, eliminating the need for air to traverse the middle section.
4Device complexity
If a single nozzle head is used, then the structure is simple, but it cannot effectively clean glass tubes of various lengths and configurations
Solution Approach 1:
The nozzle head is segmented into multiple functional sections (first, second, and third nozzle sections) with distinct opening groups positioned at different locations and orientations. This segmentation allows the single nozzle head to effectively clean glass tubes of various lengths by engaging different sections depending on the tube length and configuration.
Solution Approach 2:
The multi-section nozzle head design provides universal cleaning capability for glass tubes of different lengths and orientations. The first, second, and third opening groups can be activated selectively or simultaneously to accommodate various tube configurations, making the device versatile without requiring multiple specialized nozzles.

AI summary
A cleaning system for cleaning the inside of a glass element with a fluid includes a nozzle head including a cleaning opening for releasing a part of the fluid and pointing in a first direction and a pressure balancing opening for releasing a part of the fluid and pointing in a second direction. Two half spaces including a first one and a second one are separated by a plane which is perpendicular to a center axis of the nozzle head. A first direction vector of the first direction points in a direction at least one of towards the first half space or away from the second half space. A second direction vector of the second direction points in a direction at least one of towards the second half space or away from the first half space.
